Abstract: PURPOSE: A method for playing an optical disk and a system thereof are provided to store data which exists in one spare area of an optical disk in a spare buffer during a playing process, and to reproduce the data stored in the spare buffer if a block has a defect in a data area, thereby remarkably improving play performance of the optical disk. CONSTITUTION: A system receives a play request from a host(11). The system traces an address of a spare area corresponding to a data area of an optical disk by using an address received from the host(13). An optical pickup moves to a position of the spare area of the optical disk, and the system reads data of the spare area and stores data of the spare area in a spare buffer(15). The system sequentially decodes the data area, and transmits the data to the host(17). If a defect block exists(19), the device decodes the corresponding data by inquiring about the spare buffer, and transmits the decoded data to the host(21). If a play operation for the one data area is fully completed, the system decides whether a next spare area exists(23). If so, the system moves the optical pickup to the next spare area, reads data existing in the next spare area, and updates the data in the spare buffer(25).
